An Approach to Skew Detection of Printed Documents
In this paper, we propose an approach to estimate the text skew for printed documents. This is an important step to prevent errors in further stages of an automatic document processing system (as text segmentation). Our approach is based on the statistical analysis of the height of the connected components. In a nutshell, our algorithm is comprised of four steps: (i) removal of redundant data; ...
متن کاملSkew angle estimation for printed and handwritten documents using the Wigner-Ville distribution
A skew estimation algorithm for printed and handwritten documents, based on the document’s horizontal projection profile and its Wigner–Ville distribution, is presented. The proposed algorithm is able to correct skew angles that range between 289 and þ898 detecting the right oriented position of the page by the alternations of the horizontal projection profile. It is able of processing successf...
متن کاملSkew Estimation in Digitised Documents: A Novel Approach
In this paper, a novel and efficient method for skew detection in document images is proposed. The proposed method is based on connected component blotching and linear regression. The proposed algorithm works well irrespective of the type of script even for a wide range of skew angle (with in ±90o).

متن کاملSkew Correction of Textural Documents
Two algorithms for accurate skew detection and correction of textual documents are presented. They depend on finding a horizontal RLSA image of the skewed document. The average skew of selected black connected components in the RLSA image is considered as the skew angle for the whole document which is finally rotated in the opposite direction by that amount to obtain the final corrected image. ...
